IMPROVEMENT IN ASH-SIFTE RS Specification forming part of Letters PatentNo. 183,307, dated October 17, 1876; application filed September 25,1876.

To all whom it may concern:

Be it known that I, AUSTIN M. KETOHUM, of the city and county ofSchenectady and State of New York, have invented a new and usefulImprovement in Ash- Sifters, which improvement is fully set forth in thefollowing specification, reference being had to the accompanyingdrawings.

In said drawings, Figure 1 represents a perspective view of theashsifter, closed. Fig. 2 is a perspective View with the cover raisedand the spout down, and the sieve inclined, with the gate open. Fig. 3shows vertical, longitudinal, and transverse sections of my improvedash-Sifter. The dark hnes in the figure show the case, the sieve, therod, the arm, and the spout, all in position as when the process ofsifting is going on. The dotted lines in the'figure show the sieveinclined, the spout down, and the gate in the sieve hanging open, all inthe position as when the dumping of the coal is going on. Fig. 4 is atop' view, showing the sieve and the rod by which it is shaken forsifting the ashes. This figure also shows that the sieve is somewhatsmaller than the case, so as to allow room for the sieve to be shakensufficiently to separate the coal from the ashes. Fig. 5 shows aperspective view of the sieve and pivoted or hinged gate.

My invention has for its object to furnish, for household and otherpurposes, an improved ash-sitter that separates the unburned coalparticles from the ashes in a quick and reliable manner, without anyannoyance from dust.

The invention consists of a movable sieve with a pivoted gate, saidsieve being arranged in the upper part of an. inclosed box, and workedback and forward in said box by a rod fastened on the under side of saidsieve, and passing through the two opposite sides of said box. When thesieve is worked the ashes fall into a barrel or box beneath, while thecoal is deposited in the spoutthrough the hinged gate in the sieve,thence into a receptacle underneath the spout. This dumping process isdone by letting off the button which holds up the spout. When the spoutfalls down the sieve inclines, the gate in the sieve is freed, while theparticles of coal slide out through the gate into the spout, thence intoa receptacle to receive them. After so dumping the sieve it may bereplaced for again sifting by raising and closing the spout in the outercase, to which spout is attached a rod, which connects with the rear endof the sieve by an arm, so when the spout is raised the sieve is alsoraised by the rod to a horizontal position for again sifting, the spoutanswering the double purpose of a spout and a door to the outside case.

A in the drawing represents the outer box or case of my improvedash-sifter, which is inclosed by a tightlyfitting cover, B, hinged. tothe same on top, and also a pivoted spout, E, on the side of case A. Onthe inside of case A is a movable sieve, H, having a hinged or pivotedgate, G, on one side. Said sieve H rests and is fastened on rod 0 to theright of the center of said sieve, so it will incline readily when thesupports S S are removed at the other end. After the process of siftingis gone through with, and the coal is to be removed from the sieve, turnthe button K, and the weight of sieve H upon the rod L and arm N,connected to the spout E by joint D, will press out spout E, and thesieve H will incline to a proper angle for the coal to slide out. Therod L and arm N will draw the spout E down also, and the gate G will befreed, so the coal readily slides out and down through gate Gr intospout E to a box or other receptacle underneath for that purpose. Toreplace the sieve H for again charging it, raise the spout E to aperpendicular position and button it with button K. By this motion theconnecting-rod L and arm N, said arm N being connected firmly to therear end of sieve H, will draw the sieve H to a horizontal position foragain charging it, the gate Gr being then kept closed by being incontact with the inside of case A. While the process of sifting is goingon, gate Gr, being hung on a pivoted rod, m, swings readily out, whensieve H is lowered to the opening occupied by spout E. The rod L has auniversaljoint connection with E at D, and with the rod N at P. Thesieve is rigidly fastened to rod 0, and bears at its other side freelyon the inclined ends S S of the door and spout E 5 hence the coal issifted by taking hold of tron handle of G and reciprocating the sieve Hhorizontally, the rod 0 playing loosely in holes through the sides ofthe box A. As the case is entirely inclosed, no dust can escape whilethe process of sifting is going on, so the ash-' sifter may be used atany place without annoyance. The sifter is compactly made, easilyoperated, and of moderatecost.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- AUSTIN M. KETOHUM. Witnesses W. G. FIToH, A. O. VANVRmKEM.
